Ingredients for all recipe chicken and rice casserole
Sixteen ingredients transform into a creamy, cheesy casserole that's perfect for meal prep or weeknight dinners.
| Ingredient | Amount | Notes |
|---|---|---|
| Cooked Chicken Breast 🍗 | 2 ½ cups | Diced into bite-sized pieces |
| Long-Grain White Rice 🍚 | 2 cups | Uncooked, jasmine or basmati preferred |
| Chicken Broth 💧 | 2 ½ cups | Low-sodium preferred for balance |
| Heavy Cream 🥛 | ½ cup | Full-fat for optimal creaminess |
| Mushrooms 🍄 | 8 oz | Button or cremini, sliced thin |
| Yellow Onion 🧅 | 1 whole | Diced into small pieces |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic depth |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, aged for tang |
| Mozzarella Cheese 🧀 | 1 cup | Part-skim or whole milk |
| Butter 🧈 | 2 tbsp | Unsalted, for sautéing |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |

The chicken and rice form the heart of this dish, so prioritize quality here. For the chicken, pre-cooked rotisserie chicken saves time—just shred it yourself for better texture. If using raw, boneless, skinless breasts cook evenly. For rice, jasmine or basmati grains stay separate and fluffy, while long-grain white rice absorbs more liquid. The chicken broth should be low-sodium to avoid overpowering the delicate flavors—Swanson or Pacific Foods are reliable brands. The mushrooms and onions can be prepped ahead and stored in the fridge for up to 3 days.
No heavy cream? Full-fat coconut milk works in a pinch, though the texture will differ slightly. Substituting chicken with shrimp or chicken sausage keeps it hearty while adapting to dietary preferences. For a gluten-free option, cornstarch or arrowroot powder replaces flour for thickening. The cheese blend is key—sharp cheddar adds tang, while mozzarella provides melt. If you're dairy-sensitive, vegan cheeses can mimic the texture when combined. Fresh herbs like thyme and parsley elevate the dish, but dried versions work at one-third the amount.
This casserole reheats beautifully—just cover with foil and bake at 350°F for 15-20 minutes. It keeps well in the fridge for 4-5 days, though the cheese topping may firm up slightly. For longer storage, freeze portions for up to 3 months. To customize, add jalapeños or breadcrumbs to the cheese layer for extra texture. The leftovers make an excellent lunch the next day, especially paired with a crisp side salad.

Step-by-step instructions for one-pot creamy chicken and rice casserole
This method delivers restaurant-quality texture with minimal cleanup—creamy sauce, tender rice, and perfectly seasoned chicken.
🍳 Step 1: Sauté Aromatics and Build the Base
Melt the 2 tablespoons butter in a large, oven-safe skillet or deep sauté pan over medium heat. Add the 1 whole yellow onion and 8 oz mushrooms, cooking for 5-6 minutes until the mushrooms release their moisture and begin to soften. You'll notice the mushrooms shrink slightly and develop a golden hue at the edges.
Push the vegetables to one side of the pan and add the 4 minced garlic cloves and 0.5 teaspoon dried thyme. Stir constantly for 30 seconds until fragrant—this prevents burning while developing the aromatic base. Here's the thing: don't walk away during this step. Garlic burns faster than you think.
Sprinkle the 2 tablespoons all-purpose flour over the vegetables and stir vigorously for 1 minute to remove any raw flour taste. This creates a roux that will later thicken our creamy sauce. The mixture should look like wet sand when properly combined.
🥘 Step 2: Layer Rice and Chicken for Even Cooking
Pour in the 2.5 cups chicken broth and stir to dissolve any remaining flour bits. Bring to a gentle simmer, then reduce heat to low. Add the 2 cups uncooked long-grain white rice, spreading it evenly across the pan. You want the rice to be submerged in the broth but not packed too tightly.
Make 6 small wells in the rice and distribute the 2.5 cups diced cooked chicken breast evenly. This arrangement ensures each bite contains both rice and chicken. Sprinkle the 1.5 teaspoons salt and 0.5 teaspoon black pepper over everything, mixing gently just until combined.
Cover the pan with a tight-fitting lid and cook on low heat for 15 minutes. You'll know it's ready when you see steam escaping around the edges and the rice has absorbed about half the liquid. This initial cooking prevents a mushy texture later.
🔥 Step 3: Prepare the Creamy Cheese Topping
While the rice cooks, combine the 1.5 cups sharp cheddar cheese and 1 cup mozzarella cheese in a medium bowl. Whisk in the 0.5 cup heavy cream until smooth—this creates our signature creamy topping. The mixture should be thick but pourable, like heavy cream cheese.
Remove the pan from heat and carefully spoon the cheese mixture evenly over the rice and chicken. Use a spatula to gently fold the top layer 2-3 times to distribute the cheese mixture throughout. This step creates the signature creamy texture without making the rice soggy.
🔥 Step 4: Bake Until Bubbly and Golden
Transfer the pan to a preheated 375°F oven and bake uncovered for 25-30 minutes. You're looking for a golden-brown crust on top with visible bubbles forming in the cheese layer. The casserole is done when the cheese is fully melted and the edges are crisping slightly.
I always check for doneness by inserting a thin knife into the center—it should come out clean with no resistance. If the cheese isn't golden enough after 25 minutes, broil for 2-3 minutes on high, watching carefully to prevent burning.
🍽️ Step 5: Rest and Garnish for Perfect Texture
Remove from the oven and let the casserole rest for 5 minutes before serving. This resting period allows the juices to redistribute, ensuring each bite is creamy and flavorful. The cheese will set slightly, making it easier to serve without a runny topping.
Garnish with the 0.25 cup chopped fresh parsley just before serving. The parsley adds a fresh contrast to the rich, cheesy layers. Serve immediately while the cheese is still warm and creamy—this dish doesn't reheat well once cooled.
Pro Tips For Making All Recipe Chicken And Rice Casserole
- Sauté Mushrooms First: I learned this the hard way—tossing raw mushrooms into the casserole means they’ll steam instead of brown. Sear them in a dry pan for 5 minutes until they release their moisture and develop flavor. (Yes, even if you’re impatient like me, don’t skip this.)
- Use Cold Chicken: Hot chicken in a cold casserole mix makes the rice turn mushy. Let the chicken cool completely before adding it to the dish—this keeps the texture light and prevents a soggy final result.
- Layer Rice Last: Pack the rice in the baking dish after adding the chicken, broth, and cream. This way, the liquid distributes evenly, and the top layer doesn’t dry out while the bottom gets soggy. (Trust me, your first attempt will tell you why.)
- Skip the Pre-Bake: Most recipes call for pre-baking the casserole uncovered to thicken the sauce. Instead, stir in a cornstarch slurry (1 tbsp cornstarch + 2 tbsp cold water) during the last 10 minutes of baking. It thickens faster and keeps the texture creamy without drying out the top.
Troubleshooting great all recipe chicken and rice casserole
Mushy Rice Fix
If your rice turns out mushy, it’s usually because of overcooking or too much liquid. To prevent this, reduce the chicken broth to 2 cups (instead of 2.5) and cook the rice uncovered for the last 5 minutes of stovetop cooking.
For a second attempt, spread the rice in a single layer on a baking sheet and bake at 350°F for 10 minutes to dry it out before assembling the casserole. 💡
Cheese Not Melting
If the cheese stays clumpy or doesn’t melt smoothly, it’s likely due to low oven temperature or too much moisture. First, ensure your oven is properly calibrated—use an oven thermometer to confirm it’s at 375°F.
For extra insurance, sprinkle 1 tablespoon cornstarch over the cheese layer before baking to absorb excess moisture. If the cheese still doesn’t melt, try broiling for 1-2 minutes on high at the end, watching closely to avoid burning. 🔥
Dry or Crumbly Topping
A dry topping often means the cheese layer was too thin or the casserole was overbaked. To fix this, double the cheese amount (use 2 cups total) and cover the casserole loosely with foil for the first 20 minutes of baking.
This traps steam and keeps the cheese moist. For future attempts, remove the casserole from the oven as soon as the cheese is 80% melted—it’ll continue cooking from residual heat. 🧀
Uneven Cooking
If some parts of the casserole are undercooked while others are burnt, your oven’s heat isn’t distributing evenly. Rotate the pan halfway through baking and place it on the middle rack for consistent heat.
For future cooks, use an oven-safe skillet with sloped sides (like a Calphalon or All-Clad) to help heat circulate better. A light-colored pan also reflects heat more evenly than dark pans. ⚡
Sauce Too Thin
A runny sauce usually means the roux wasn’t cooked long enough or the flour wasn’t properly incorporated. To thicken it, whisk 1 tablespoon cornstarch with 2 tablespoons cold water, then stir it into the sauce while simmering.
For prevention, cook the flour and butter roux for 2-3 minutes until it turns a golden color before adding the broth. This ensures a proper thickening base. 🥄
Chicken Too Dry
Overcooked or tough chicken can ruin the texture. Always use pre-cooked chicken (rotisserie or poached) and shred it finely for even moisture distribution. If using raw chicken, poach it in broth instead of baking—this keeps it juicy.
For a second attempt, reheat the chicken in a splash of broth before adding it to the casserole. This adds moisture back into the meat. 🍗

Frequently asked questions
Can I make this casserole with frozen chicken instead of cooked?
Yes, but you'll need to adjust the cooking time. Use 1.5 pounds frozen chicken breasts (not breaded) and bake them uncovered at 375°F for 20 minutes before adding to the casserole. This ensures the chicken cooks through without drying out. For best results, thaw the chicken first in cold water for 30 minutes to speed up the process.
What's the best way to reheat leftovers?
Reheat covered with foil at 350°F for 15-20 minutes until warmed through. For a crispy topping, uncover for the last 5 minutes of reheating. Microwaving isn't recommended as it can make the cheese rubbery. The casserole keeps well in the fridge for 4-5 days, though the texture may change slightly after 3 days.
Can I use instant rice instead of long-grain?
Instant rice works but requires adjustments. Reduce the broth to 1.5 cups and cook the rice for only 10 minutes on the stovetop (no need to cover). The rice will absorb liquid faster, so monitor closely. For best results, use jasmine instant rice which has better texture than basic instant varieties.
How can I make this dish gluten-free?
Replace the all-purpose flour with 2 tablespoons cornstarch and use gluten-free chicken broth. For the rice, choose certified gluten-free varieties like jasmine or basmati. Check cheese labels too—some contain gluten as an anti-caking agent. The rest of the recipe remains unchanged, delivering the same creamy texture.
Why does my cheese topping sometimes get oily?
Oily cheese topping usually means the cheese was too warm when mixed or the cream separated. Always whisk the cheese mixture over ice water to keep it cool, and use full-fat heavy cream (not light cream). For extra stability, add 1 tablespoon cold butter to the cheese mixture before spreading. This helps emulsify the fats and prevents separation.
